Introduction

GB/T 46639 "Terminology for Foundry Machinery" covers foundry machinery used in foundry production.

Casting, as a metal heat treatment process that involves filling a mold with molten metal and allowing it to solidify to obtain parts or part blanks, has a long history.

History, and its technology is constantly developing and changing. Depending on the mold used, or the method of filling or solidification of the molten metal, it varies.

Depending on the method, there are many different casting processes, such as sand casting, investment casting, lost foam casting, die casting, low-pressure casting, and metal mold casting.

Force casting and centrifugal casting, etc.

GB/T 46639 "Terminology for Foundry Machinery" serves as the fundamental standard for foundry machinery, and the definitions of each concept selected are applicable to the casting industry.

The general application scope of machinery covers various casting equipment for different casting methods and different production process stages.

GB/T 46639 "Terminology for Foundry Machinery" is proposed to be divided into the following six parts.

---Part 1: Fundamentals. The purpose is to define the basic terminology and definitions of casting machinery.

---Part 2: Molding, Core-Making Machines and Other Non-Permanent Casting Equipment. The purpose is to define molding, core-making machines and other non-permanent casting equipment.

Terminology and definitions for mold casting equipment.

---Part 3: Die Casting Machines and Other Permanent Casting Equipment. The purpose is to define the technical specifications of die casting machines and other permanent casting equipment.

Language and definition.

---Part 4: Shot blasting machines and other casting cleaning equipment. The purpose is to define shot blasting machines and other casting cleaning equipment.

Equipment terminology and definitions.

---Part 5: Cupolas, Casting Equipment and Ladles. The purpose is to define the terminology and definitions for cupolas, casting equipment and ladles.

---Part 6: Other. The purpose is to define the casting machinery-related terms and definitions not covered in Parts 1 through 5.

This document is Part 2 of GB/T 46639, and only covers the terminology and definitions of molding, core-making machines and other non-permanent casting equipment.

The scope includes various molding machines, core-making machines, sand-shedding machines, molding sand preparation and sand recycling equipment, lost foam casting and investment casting equipment, and other related equipment.

Basic concepts of the structural features and functions of equipment, important mechanisms and components, main process flow and parameters.

The development of the GB/T 46639 series of standards, "Terminology for Foundry Machinery," has laid the foundation for the formulation and revision of standards and technical documents in the field of foundry machinery.

It provides a unified standard for technical terminology in conjunction with relevant scientific and technological publications.

3D Vibrating Table

A vibratory compaction table capable of achieving compaction via vibration in the X, Y, and Z directions.

A liquid control system for two hardeners, A and B, with different properties, the pump flow rate is adjusted via a frequency converter to regulate the dosage of A and B in real time and the amount added each time.

An automatic control system that ensures reasonable hardening time and stable strength of sand molds.

A device for sorting out defective or prototype parts before sand removal.

A machine that uses compressed air to press wax molds.

static pressure molding air-flow-squeezemolding the molding method employs airflow pre-compaction and pressure head final compaction.

static pressure molding line air-flow-squeezemoldingline an automated molding line connects a static pressure molding machine (main machine) and auxiliary machines with mold or sand box conveying equipment according to the process flow.
